Easy outpost liberation
Use the following trick to liberate an outpost without being detected. When you find an outpost that has a caged animal (for example, a bear or tiger), find a good hiding location inside the outpost that has a good view of the cage but far from it. Select any weapon with a sound suppressor and shoot at the cage. Make sure no guards are close to you when you shoot. Eventually the door to the cage will break and the animal inside will be freed. All the guards and guard dogs will turn their attention to that animal. The freed animal will proceed to "liberate" the outpost for you. All you have to do is remain hidden until it is over. Doing this twice will allow you to to unlock the Ninja Step skill, which makes you very silent. It is best to scan the entire area with your camera beforehand so you can see the progress of the animal when you free it. It also makes for a great show.
